We need 8 stripes 20 cm on 1 cm.
Roll them with a glue, just like on the picture (like we usually do snail, but this time glue stripes, moving it on the lower part of the stripe).
Cut protruding edges, in order to make it straight.
Make small cuts on the sides in order was easy to attach (wavy cut).
Attach 3 fist pieces and start gluing on the sides. Make wavy cuts around, where other horns are, in order it fit better.
So, I just glued these horns around where I thought, enough space for it, you do, how you like.
Here you can, I attached together 6 horns. The main 3 at the middle, 2 on the sides and 1 between horns on the right side on the picture.
Making cuts for fitting between horns and gluing it.
You can decorate each horn with beads, I decided to leave it just the way it is.
